ports-or blocks upon the car.

In the drawings accompanying this specification and forming a part thereof, the preferred embodiment of the invention isillus trated, in which F i'gurel is a fragmental side elevation ofy I a portion of a car equipped with' the improved roofing. Fig. 2 is a cross sectional View taken on the line 2-'2 of Fig. 1. Fig. 3 is an enlarged sectional detail taken on the line 3-3 of Fig. 2. Fig. 4. is a sectional detail taken on the line 4--4 of Fig. 2.

Referring to the drawings in which similar `reference numerals designate corresponds ing parts throughout the several views, the numerals 5 designate the car side walls, 6 the side fascia, and 7 the longitudinal beams'.

The metallic rooting 9 is corrugated and overlaps the entire width of the car, and extends the side fascia by referring to Fig. 2.v The roof is made up of a -series of lapping roof sections or blanks which have their corrugations extending transversely. The metallic roofing 9 rests upon the tongue and groove boards 10 which in turn are supported vby the wooden nailing strips 11 housed I within metallic vchannels 12.

In order to rigidly secure the metallic rooling to the car and without necessitating that the said'rooling be punctured, such as is necessary when bolts pass therethrough, pairs of tierods 13 are provided, which rods have their ylower or remote ends engaged through the longitudinal beams 7, the side fascia 6, the ends of the corrugated sheets, reinforcing strips 26, and apertures 15 in clamping plates 16. The clamping plates 16 are rigidly secured to the side fascia and prevent the wearing of the roong at the point where the rods pass through the side fascia. Each rpair of rods 13 is Vdisposed above vone of the grooves of the corrugations and the rods are prevented from contacting --with the metallic roofing lby the wooden spar-r strips 17 seated in the respective grooves of the corrugations and whichy are provided with the grooves 18 therein receiving the rods 13. Nuts 14 are threaded upon the lower ends of the rods to anchor them to Y The -rods terminate' the sides of the car.

femm. l

short of the center of the roofing and arev threaded, as at 19, and the adjacent ends are vengaged to a yoke A21.

Disposed between the adjacent ends of each pair of tie rods 13, is an elongated sup:

porting block 23 for the. running board 2.27,'

and the corresponding yoke 2l is secured by means vof bolts or lother securing means24, to one side of the block 23. The-yoke 21,'v

which is in the form of a strip, has its ends extending angularly beyond the endsmof the blockl 23 and lprojecting downwardly .and

seated in the groove overv whichthe tie rods 13 are disposed, the block 23 'also being seated within the said groove at the central portion thereof. The adjacent or inner ends of the rods 13 are engaged through the angular ends of the yoke or strip 21, and beary nuts 25 seated outwardly the yoke or strip. l In order to'l strengthen) the metallic roofagainst the ends of ing, the sinuous. reinforcing strips 26 `are riveted, as at 27, to the ends of the roong sheets.

rIhe channel beam l2 supports the nailing Tlf" strip 11 therein and 'the said parts vare secured together by bolts 28, thus preventing the rising of the nailing strip llabove the bottom of the channel. The tongue and groove boards 10 are nailed to the nailing strip and the metallicbottom of the channel presents a surface which delects and clenches the nails against the bottom of the nailing strip to prevent the boards from loosening. The ends of the channel are bent p.

downwardly and outwardly, and are rigidly -secured to the longitudinal beams 7, thus forminga rigid structure. In order to brace the arcuate channels 12, angle iron' braces 30 are riveted to the channel, as at 31,' at their extremities and plates 32 .are secured to the braces and channels, whereby the entireY structure will be extremely rigid and capable of withstanding considerable weight.

The section in Fig. 2 does not disclose two overlapping portions of the metallic roofing as the same would tend vto confuse the figure but this feature has been illustrated in Figs. 3 and 4, and it is to be noted that at each overlapping joint of the'metallic roof sections, the tie rods 13 are' provided, thus `sesol section upon the other. The nuts may be tightened so as to produce the required tension upon the rods 13 and' which insures that the required pressure exerted in a downward direction upon the metallic roofing against rEhe strong and rigid manner in which the channels, e gether and to the side walls of` thecar' ren-4 ders it unnecessary to provide kany ridfgepole and purlins as is the ordinary practice.V v

Particular attention is directed to the fact that the blocks 23 and yokes 21 are "each,

seated in the respective'grooves of the; core rugations off the rooting, whereby the blocks 23 will effectively supporti the running board 22 secured thereon, without transmittin'gthe strains 'toi any appreciable extentv to the yokes i d. 2L 'lihugthe bloeks" 23will serve as a oushf Aion engaging the-roofing `for preventing the the 'running board, from injuring the v Furthermore, the ends of the yokes upo ams and braoes` are secured toinsane@ 21 being'seated within thegrooyes, will enable the blocks 23 to be loosened or removed v without 'aectigthe utility of the tie rods 13.
